Study on a Digital Ultra-Brief Intervention During Wait Times for Psychotherapy

Summary

The OPTIBRIEF study investigates different versions of a digital ultra-brief intervention (UKADO - a German acronym for ultra-brief intervention against anxiety and depression online) during the waiting period for psychotherapy. Using a factorial trial design, the components 1) intervention content, 2) human support, and 3) expectation-fostering elements will be examined. After completing initial questionnaires and participating in a diagnostic interview, participants are randomly assigned to one of eight groups and work through a specific version of UKADO. The program can be completed in a session of approximately 60 minutes, after which the exercises should continue to be used. Participants then complete another set of questionnaires at specific time points (after 2 weeks, 5 weeks, 9 weeks, and 24 weeks). A selection of participants also takes part in another telephone appointment to assess experiences with UKADO. With the OPTIBRIEF study, the investigators aim to determine which version of the program is most suitable for individuals waiting for a psychotherapy slot. To this end, the investigators examine the effects on anxiety and depression symptom severity, as well as aspects such as participants' experiences with the program.
